Kitplanes is doing a comprehensive survey for current and prospective homebuilders.
Whether you have a homebuilt or dream of building one, they want to know everything about it.
Some questions are US centered, but not much.
It is done with the kit industry. The idea is to help Kitplanes be a better magazine and the industry to know what the market looks for.
